The immunomodulatory drugs lenalidomide and pomalidomide bind to cereblon (CRBN), a substrate receptor of the CRL4A E3 ligase complex, to initiate degradation of neosubstrates critical for cell survival. Recently, nonlenalidomide or pomalidomide CRBN binders, known as alternate glutarimides, have gained popularity, offering potential degraders with varying physicochemical properties. Specifically, 3-substituted indazole derivatives have emerged as potent CRBN binders. We developed conditions for the direct cross-coupling of unprotected glutarimides with amines, streamlining the synthesis of alternative CRBN binders. This manuscript describes the rapid synthesis of 30 CRBN binders, their characterization as potential degraders and a cryo-EM structure of the CRBN/DDB1 with a representative compound (). |
